At a hot spot, the mantle directly beneath the crust is hotter than usual. This hot mantle material partially melts. The molten material, called magma, rises through the crust and erupts onto the surface for form volcanoes.

How do hotspots form?
Hotspots are thought to form due to mantle plumes. This is the upwelling of high temperature material from deep within the mantle. This high temperature material causes partial melting of the shallow mantle and overlying crust leading to a "hotspot" and volcanism.
How does heat in the Earth's mantle relate to hotspots and geysers?
Hotspots and geysers transfer heat from the Earth's mantle to the Earth's surface.
What type of landform is formed by a mantle plume?
Hot spot and izzi rocks
Why do diamonds form in the mantle?
Diamonds are able to form in the Earthâ??s mantle. This is because there is carbon and great amounts of heat and pressure.
How do hotspots affect humans?
Mantle plumes - areas of unusually hot rock that can punch through the Earth's crust to create volcanoes like the Hawaiian island. Not only do they form land, which humans can live on, they create hazards like volcanoes (Hawaii itself is a volcano) and even super volcanoes such as Yellowstone, which allegedly has the potential to wipe out large areas of life on the globe. The affects of hotspots are all of those associated with volcanic activity without the fault-line processes linked with tsunamis and earthquakes.
Is it true that hotspots form where a plume of magma rises through the crust from mantle?
True

What is the belt of a volcano called?
a belt of volcanoes is called an island arc, they are formed from Hotspots/Mantle Plumes
How can a chain of seamounts be used to tell which way the pacific plate is moving?
Seamounts are submarine volcanoes that form on the ocean floor. They are formed by hotspots (which are hypothesised to be the result of mantle plumes although there is some controversy over this theory in the geophysical community) which cause melting of the crust. These hotspots in the upper mantle are in fixed locations, so as the tectonic plate moves over the hotspot a chain of seamounts forms creating a line in the direction of the plate movement.
How do geologists suggest that hot spots are related to plate tectonics?
A hotspot's position on the Earth's surface is independent of tectonic plate boundaries, and so hotspots may create a chain of volcanoes as the plates move above them. ... One suggests that hotspots are due to mantle plumes that rise as thermal diapirs from the core-mantle boundary.
What name is given to the area where volcanoes often occurs because convection in the earths mantle produces a column of magma that rises into the crust?

What causes volcano's to form?
Volcanoes can be caused by mantle plumes. These so-called hotspots can occur far from plate boundaries. Hotspot volcanoes are also found elsewhere in the solar system, especially on rocky planets and moons. Volcanoes can also form where there is stretching and thinning of the Earth's crust.
